| Estudo sobre a fenologia de reproducao de especies arboreas (angelim-pedra, copaiba, cupiuba, jatoba, louro-gamela) no Amazonas, visando garantir o estoque regular de semente e atender as necessidades de formacao de mudas dos programas de reflorestamento. Angelim-pedra produz inumeros sementes, que sao dispersas pelo vento; copaiba produz numerosas sementes, que sao dispersas por aves; cupiuba, apesar de produzir bem anualmente, tem suas sementes em estagio de maturacao muito predadas por aves; jatoba tem frutificacao escassa e irregular, os macacos sao os principais predadores; louro-gamela frutifica abundantemente, suas sementes sao relativamente pequenas, o que dificulta a coleta, e os animais predadores alimentam-se dos frutos ainda verde. De acordo... |

| O objetivo deste estudo foi caracterizar a fenologia, a produção e os teores de compostos químicos associados à qualidade de frutos de acessos de umbuzeiro (Spondias tuberosa Arruda) na Embrapa Semiárido, Petrolina, Pernambuco, sob condição de dependência de chuva. As avaliações foram realizadas nas safras 2012-2013, 2013-2014 e 2014-2015, caracterizadas por índices de precipitação pluviométrica abaixo da média histórica. Eventos de floração foram registrados de setembro a janeiro. O enfolhamento ocorreu em resposta às primeiras chuvas dentro de cada ano-safra. A produção concentrou-se nos meses de março a abril. Os acessos BGU 37, BGU 48, BGU 52 e BGU 55 apresentaram maior potencial para a produção de frutos, com características de qualidade química de... |

| Marine water quality monitoring and subsequent management require to know when a specific event like harmful algae bloom may occur and which environmental conditions and pressures lead to this event. So, event detection and its dynamic understanding are crucial to adapt strategy. An algorithm is proposed to identify curves mixture and their dynamics features - initiation, duration, peaks and ends of the event. The approach is fully unsupervised, it requires no tuning parameters and is based on Expectation Maximization process to estimate the most robust mixture according to fixed criteria. A complete framework is proposed to deal with a univariate time series with missing data. The approach is applied on Chlorophyll- a series collected weekly since 1989.... |

| Seven new species of the genus Aleiodes Wesmael, 1838 (Braconidae: Rogadinae) are described and illustrated: A. abraxanae sp. n., A. angustipterus sp. n., A. artesiariae sp. n., A. carminatus sp. n., A. diarsianae sp. n., A. leptofemur sp. n., and A. ryrholmi sp. n. A neotype is designated for each of Aleiodes circumscriptus (Nees, 1834) and A. pictus (Herrich-Schäffer, 1838), and both species are redescribed and illustrated. Aleiodes ochraceus Hellén, 1927 (not A. ochraceus (Curtis, 1834)) is renamed as A. curticornis nom. n. & stat. rev., and redescribed and illustrated. Aleiodes bistrigatus Roman, 1917, A. nigriceps Wesmael, 1838, and A. reticulatus (Noskiewicz, 1956), are re-instated as valid species. A lectotype is designated for Aleiodes... |

| The nesting behavior of Podium denticulatum Smith was studied on the campus of Ribeirão Preto of the Universidade de São Paulo, SP, Brazil, from September 2003 to August 2005. The wasps established their nests in bamboo canes ranging from 11.4 cm to 26.2 cm in length and from 0.7 cm to 1.8 cm in internal diameter. Podium denticulatum nested almost exclusively in the hot and wet season (September-April), producing at least five generations per year. The cell provisioning was made with adult and nymphal cockroaches (Blattellidae) which were arranged venter-up and with the head inward toward the inner end of the cell. The construction of a temporary closure occurred in cells that took more than one day to be provisioned. The cells provisioned with a greater... |

| Reproductive seasonality in tropical freshwater fishes is strongly influenced by rainfall. In lowlands, floods spill laterally to floodplains and fishes usually breed during the flooding season. In mountain rivers, floods are sudden and flush out aquatic organisms. Fishes in mountain rivers usually breed during dry seasons, what has been hypothesized as a strategy to reduce mortality due to strong floods. If that is the case, mouth-brooding fishes should suffer less from strong floods and should have more prolonged breeding seasons in mountain rivers. Here we investigated the breeding activity of a mouth-brooding cichlid (Geophagus steindachneri) in a mountain river in Colombia using three kinds of evidence: monthly variation of gonad weight, macroscopic... |
